Abstract |
Carbon materials are one of famous electrocatalyst that have been studied as alternative to platinum in dye-sensitized solar cells. However, most of the research focused on performance and have not been fully considered all underlying factors that dictate their electrocatalytic activity; the current understanding of the electrocatalytic activity of nitrogen-doped carbons is limited. In addition, the synergistic effect of metal nanoparticles embedded in nitrogen-doped carbon, which was recently demonstrated as a facile way to boost the electrocatalytic activity of carbon, remains elusive. In this works we synthesized Co/N–Cs by carbonizing zeolitic imidazolate framework-67 (ZIF-67) at various temperatures. Using these materials, we sheds light on these unknown aspects of carbon’s electrocatalytic activity by carrying out a systematic investigation of nitrogen-doped carbon with incorporated cobalt nanoparticles with the aid of density functional theory calculations and in-depth electrochemical analysis. |
